Turbulent energy cascade through equivalence of Euler and Lagrange motion descriptions and bifurcation rates [PDF]

Journal of Applied and Computational Mechanics, 2021
This work analyses the homogeneous isotropic turbulence by means of the equivalence between Euler and Lagrange representations of motion, adopting the bifurcation rates associated with Navier-Stokes and kinematic equations, and an appropriate hypothesis ...

Global testing against sparse alternatives in time-frequency analysis [PDF]

, 2016
In this paper, an over-sampled periodogram higher criticism (OPHC) test is proposed for the global detection of sparse periodic effects in a complex-valued time series.

Between children and parents: Housing (in)dependence and “growing up” [PDF]

Sociologija, 2012
In this paper we explore the relationship between financial and residential independence of young people and some aspects of their psychological separation from parents.

A Lagrangian Stochastic Model for the concentration fluctuations [PDF]

Atmospheric Chemistry and Physics, 2005
A Lagrangian Stochastic Model for the two-particles dispersion, aiming at simulating the pollutant concentration fluctuations, is presented. Three model versions (1-D, 2-D and 3-D) are tested.

Second order statistics based blind source separation for artifact correction of short ERP epochs [PDF]

, 2003
ERP is commonly obtained by averaging over segmented EEC epochs. In case artifacts are present in the raw EEC measurement, pre-processing is required to prevent the averaged ERP waveform being interfered by artifacts. The simplest pre-processing approach

A Comparative Analysis of Methods for Determining Odour-Related Separation Distances around a Dairy Farm in Beijing, China

Atmosphere, 2019
Concentrated animal feeding operations (CAFOs) such as dairy farms are a source of odorous compound emissions. In this study, by identifying relevant odour sources within a 300-head dairy farm and quantifying their emissions, we determined the separation

The statistics of wide-separation lensed quasars

, 2000
The absence of any wide-separation gravitational lenses in the Large Bright Quasar Survey is used to place limits on the population of cluster-sized halos in the universe, and hence constrain a number of cosmological parameters.

Closed-loop separation control over a sharp edge ramp using Genetic Programming [PDF]

, 2015
We experimentally perform open and closed-loop control of a separating turbulent boundary layer downstream from a sharp edge ramp. The turbulent boundary layer just above the separation point has a Reynolds number $Re_{\theta}\approx 3\,500$ based on ...

Shift-Invariant Kernel Additive Modelling for Audio Source Separation

, 2018
A major goal in blind source separation to identify and separate sources is to model their inherent characteristics. While most state-of-the-art approaches are supervised methods trained on large datasets, interest in non-data-driven approaches such as ...

Single-Channel Blind Image Separation Based on Transformer-Guided GAN

Sensors, 2023
Blind source separation (BSS) has been a great challenge in the field of signal processing due to the unknown distribution of the source signal and the mixing matrix.
